  • EVALUATION OF THE ECHOCARDIOGRAM AS AN EPIDEMIOLOGIC TOOL IN AN ASYMPTOMATIC POPULATION CIRCULATION VALDEZ, R. S., MOTTA, J. A., London, E., Martin, R. P., Haskell, W. L., Farquhar, J. W., Popp, R. L., HORLICK, L. 1979; 60 (4): 921-929

    Abstract:

    An asymptomatic adult population of 196 men and women was studied with the echocardiogram to derive age- and sex-specific "normal" values for a number of clinically used echocardiograhic variables. The results are in general agreement with previously published normal values. Body position during the examination, age and sex influence the echocardiographic results; body surface area correction normalized most of these effects. The prevalence of occult abnormalities determined by the echocardiogram is 7%; the most common finding was mitral valve prolapse. Inter- and intraobserver variability was assessed. The interobserver differences found on analysis are statistically, but not clinically , significant. The echocardiogram appears to be a suitable tool to use in epidemiologic studies to detect selected cardiac abnormalities, but is limited for this purpose because some subjects in such a population cannot be adequately examined.
